Hello I'm 26 I've been having very bad pains in my right breast for a cpl mnths now. But the past couple of days I've been having poison under my left underarm. I'm worried it could be cancer. Someone please help me I'm scared :(

Poison?

Poison?
Poisoned? No ma'am don't think so what else could it be

You said in your question that you have "been having poison under my left underarm."

Im so sorry I meant pain

I have lost track of the number of things that this could be. Only a medical professional can determine whether this is cancer, or a pinched nerve, or a slipped disc, or a heart disease, or... well you get the picture.

Even with the best medical write ups it is impossible to say what is going on. I would get it checked out sooner rather than later.
